A centrifugal casting furnace plate

Abstract

This application discloses a centrifugal casting furnace tray, comprising: a centrifugal casting furnace tray capable of slowly tightening and compacting bauxite using side plates. It includes: a base plate; and four side plates arranged in a circumferential array, the side plates being rotatably hinged to the base plate, and the four side plates being able to open or retract relative to each other. A mold shell containing a wax model is placed on the base plate, positioned in the middle of the four side plates. Bauxite is filled between the side plates and the mold shell. Nuts are screwed onto the mold shell, slowly tightening and compressing the side plates, thus compacting the bauxite. The tightening force of the nuts avoids concentrated impact, solving the problem of mold shell damage easily caused by hammering and compressing the side plates during bauxite filling.

Description

Technical Field

[0001] This invention relates to a centrifugal casting furnace tray, belonging to the technical field of casting auxiliary equipment. Background Technology

[0002] After sandblasting, the wax pattern of the casting needs to be heated to melt the wax and expel it. To ensure that as much wax as possible is expelled, the mold shell needs to be fixed on a centrifugal casting furnace plate. By rotating the centrifugal casting furnace plate, the wax inside the mold shell is discharged under centrifugal force.

[0003] When the existing mold shell is fixed on the centrifugal casting furnace plate, the mold shell is placed on the bottom plate of the plate, and then the side plate is fixed on the bottom plate with bolts to block the side of the mold shell for limitation. The side plate and the side of the mold shell are filled with bauxite. When the bauxite on the side of the mold shell is not filled, the side plate is knocked and squeezed to fill the bauxite. The concentrated impact force during the knocking can easily cause the mold shell to break. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a centrifugal casting furnace tray.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a centrifugal casting furnace tray, comprising:

[0007] It can achieve centrifugal casting of bauxite in a furnace tray that slowly tightens the side plates to compact the bauxite.

[0008] Includes: chassis base plate;

[0009] There are four side plates arranged in a circular array. The side plates are rotatably hinged to the bottom plate of the disk. The four side plates can be opened or retracted relative to each other.

[0010] The bottom plate of the pan is provided with slots at the four corners for fixing the rotating parts of the centrifugal casting furnace.

[0011] An adapter is fixed on the bottom plate of the plate. A rotating lug is rotatably hinged to the adapter via a rotating shaft. A side plate is fixedly connected to the rotating lug.

[0012] There are four adapters and four rotating ears. The four rotating ears correspond to the four side plates. The four side plates can be rotatably hinged to the bottom plate of the chassis through the adapters of the rotating ears.

[0013] It also includes a screw that tightens the side plates, with opposite side plates being tightened together by the screw; the screw located on the outside of the side plate is screwed with a nut, which tightens the side plate when screwed onto the screw.

[0014] The side plate is provided with mounting holes, and an elastic deformable element is inserted into the mounting holes with an interference fit.

[0015] The beneficial effects of this invention are as follows: the mold shell with wax mold inside is placed on the bottom plate of the plate, the mold shell is located in the middle of the four side plates, the space between the side plates and the mold shell is filled with bauxite, and the nuts are screwed on the nuts to slowly tighten the side plates, so that the opposite side plates are tightened and the bauxite is compacted. Since the screwing force of the nuts will not be concentrated, the problem of the mold shell being easily damaged when the side plates are hammered and squeezed to fill the bauxite is solved.

[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0019] like Figure 1 As shown.

[0020] A centrifugal casting furnace tray according to this application includes:

[0021] The bottom plate 1 has slots 11 at its four corners. The bottom plate 1 is fixed to the rotating parts of the centrifugal casting furnace through the slots 11. The bottom plate 1 can be driven to rotate inside the centrifugal casting furnace.

[0022] The base plate 1 is welded with an adapter 12, and the adapter 12 is rotatably hinged with a rotating shaft. The rotating ear 21 is welded and fixedly connected to a side plate 2. There are four adapters 12 and four rotating ears 21, and the four rotating ears 21 correspond to the four side plates 2. The four side plates 2 are arranged in a circumferential array and are rotatably hinged to the base plate 1. The four side plates 2 can be opened or retracted relative to each other.

[0023] It also includes a screw 3 for tightening the side plate 2, with the opposing side plates 2 being tightened together by the screw 3. The screw 3 located on the outside of the side plate 2 is screwed with a nut 31, which tightens the side plate 2 when screwed onto the screw 3.

[0024] The side plate 2 is provided with mounting holes (the shell is not shown in the figure). An elastic deformation member 4 is inserted into the mounting hole with an interference fit. The elastic deformation member 4 can be composed of a spring or the like, and the elastic deformation member 4 can undergo elastic deformation.

[0025] In use, the mold shell containing the wax model (not shown in the figure) is placed on the base plate 1 of the tray. The mold shell is positioned in the middle of the four side plates 2. The four side plates 2 are rotated inward on the base plate 1 to be in an upright state. Screws 3 are installed through the opposite side plates 2 and nuts 31 are screwed on for tightening. Bauxite (not shown in the figure) is filled between the side plates 2 and the mold shell. Then, the nuts 31 are screwed on to slowly tighten the side plates 2, so that the opposite side plates 2 are tightened and the bauxite is compacted. The screwing force of the nuts 31 does not concentrate the impact, which solves the problem that the mold shell is easily damaged when the side plates are hit and squeezed to fill the bauxite.

[0026] The elastic deformation member 4 is inserted into the side plate 2 with an interference fit to abut against the bauxite. The elastic force of the bauxite elastic deformation member 4 maintains the pressure force at the point where the bauxite is partially collapsed.
